Femoral head osteochondritis dissecans in a child.

This case report describes an early-adolescent boy with an osteochondritis dissecans (OCD) lesion of the left femoral head secondary to significant acetabular dysplasia and coxa valga of the proximal femur. Patient underwent left proximal femur varus osteotomy. Follow-up imaging demonstrates healing and resolution of the OCD lesion. Future plan for left hip is periacetabular osteotomy, following triradiate cartilage closure, to correct acetabular dysplasia. The aim of this case report is to support clinicians in the assessment and treatment of this rare condition.
